摘要
针对混合动力汽车用异步电动机能量需要双向流动的特点,基于TMS320F2812数字信号处理器对电机驱动系统进行了设计,采用基于空间矢量PWM的直接转矩控制策略控制电机转矩,且能够有效的控制电机处于电动运行和发电运行状态,电机速度控制精度高。针对控制策略进行了必要的仿真,仿真和试验结果验证了系统的有效性。
According to the bidirectional power flow characteristic of induction motor which was used for hybrid electric vehicle, a novel system for driving the motor based on DSP TMS320F2812 is designed. The system adopted direct torque control strategy, based on space vector PWM technique, which could control the motor with fast torque response and precise speed track. The simulation is essential to validate the system structure, control strategy. The result of simulation shows the feasibility and effectiveness of system.
